New Firmware Boosts Sigma 150-600mm AF by 50%

sigma firmware 2016

Sigma have announced a new firmware update for the Sigma 150-600mm f/5-6.3 DF OS HSM lens (both sport and contemporary models). This update is relevant for lenses in the Canon or Nikon mounts. The firmware update is claimed to increase autofocusing speed of the lens by between 20% and 50%.

The firmware can be downloaded from the Sigma website. To install the update, Sigma users will need to have the Sigma USB Dock to make adjustments directly to the lens themselves. If you don’t have the dock, you can send your lens away to Sigma to have the adjustments made for you. The dock is relatively inexpensive and allows you to make these adjustments at home. The dock can be bought for both Nikon and Canon fits.
